Danny Green and Fred VanVleet each scored 10 points as Toronto bounced back from its largest defeat of the season, a 29-point loss Friday at Orlando.

“They definitely mucked up the game and made it ugly and dirty and slow,” VanVleet said of the Bulls, who have lifted their defensive intensity under new coach Jim Boylen. “Give them credit for that, but you’ve got to be able to win in different ways.”

After setting season-lows in made baskets (28) and field goal percentage (.295) at Orlando, the Raptors got off to a rough start against the Bulls. They scored 14 points in the first quarter, matching their fewest in any frame this season.

Leonard scored 12 points in the decisive fourth, going 8 for 8 at the free-throw line.

“It was an uphill fist fight the whole way,” Toronto coach Nick Nurse said. “We found a way to get to the basket eventually.”

Lauri Markkanen had 18 points and 10 rebounds, and Wendell Carter Jr. had 16 points and 11 rebounds for the Bulls, who didn’t score for the first 3:19 of the fourth.

“I thought we battled,” Boylen said. “For about 36 to 38 minutes, we controlled the game, we controlled the tempo. I’m really proud of our guys.”

The Bulls’ Zach LaVine fouled out with 13 points. It was a poor shooting night for LaVine, who went 3 for 17, including 0 for 3 from 3-point range.

“I’m still coming off this ankle [injury] so I don’t have the same lift, but I’ve got to make them regardless,” LaVine said. “Just one of those days. I wish I could go back and make them.”

Kris Dunn scored 14 points, and Justin Holiday and Chandler Hutchison each had 11 as the Bulls fell to 5-8 under Boylen.

Raptors guard Kyle Lowry (sore lower back) sat for the seventh time in eight games. Toronto is 5-3 without the four-time All-Star.

Ahead, 68-65, to start the fourth, the Raptors got back-to-back 3-pointers from Delon Wright and Siakam and held a 74-65 lead at 10:10.

Carter ended the Bulls’ drought with a hook shot at 8:41. They missed 12 of their first 15 shots in the final quarter.

Markkanen’s 3 with 1:21 left brought the Bulls within 85-82, but Leonard answered with a pair of free throws. After a missed shot by Dunn, Siakam was fouled and made a pair, giving Toronto an 89-82 advantage with 25 seconds to go.

“We gave them 45 points off things I think we’ve got to control better,” he said.
